Software Reloading

We get a lot of calls each week sounding like…

Customer: My control has a 301 alarm. How do I clear it?

Our Technician: Your control’s memory is corrupted. You will have to clear the memory and reload from your backup.

Customer: What is a Backup???

If a backup has been made, getting back on line is easy. Without a backup, the caller is faced with a very difficult – and usually expensive – recovery.

We would need to locate the critical data in the CNC that customizes the control to that particular machine tool. We must spend time to restore the machine parameters, macro programs, offsets, and sometimes the machine interface ladder.

It may take several days until the machine is running again at full efficiency.

The best solution is to avoid the problem in the first place. Make sure you have backups of every control in your plant. Make sure those backups are current. If you need someone to come in and make those for you, contact us and we will set up a service call and make the backup disks for you. If you can make them yourself, great. Just.. Also, make sure your backups are not corrupt.

You need backups of all the pertinent files.CNC (or system) parameters (including options)

  • Diagnostics
  • Part programs: If you want to save these make sure to look out for macros! PMC parameters (timers, counters, keep relays)
  • Pitch error compensation data (maybe)
  • Custom macro variables (maybe)
  • Tool offsets (maybe) Work coordinate offsets (maybe)

You may need backup of the ladder program.

Recently we have had a lot of calls about older controls that are storing the ladder in a battery-backed development board instead of ROM.

If you have one of these systems, you should make backups immediately, and arrange to have a set of ROMs burned. Losing the ladder in your control is as disastrous as losing parameters.

Our Capabilities:

  • Backup system files 
  • SRAM data backup 
  • System data backup 
  • Software recovery


We recommend that you backup your entire control at regular intervals (annually is good), and whenever important information has changed, such as updated pitch error comp, adding/removing scales, etc.

Each backup should be clearly marked with the date and which machine it goes to (use a serial number machine tag number). If you are using floppy disks for backups, use a NEW disk for each backup you make. This reduces the wear and tear on the fragile disks, and provides a safety net if your latest backup goes bad. You can fall back to the previous backup and simply work to recreate the changes. If you are using some other media, continue to keep older versions of your backup in case the most recent gets damaged.

Open systems add an additional element to the backup equation. Hard disks fail, and data gets garbled due to improper shutdowns, tampering or computer viruses.

If you use the “reload the operating system and then reinstall all the software” technique of reconstruction, the job will take hours. For that reason, we recommend that you purchase a disk backup package such as Symantec Ghost, and make a complete image of the hard disk. With this kind of software, restoring your hard disk takes less than an hour – and when you are done, everything is configured exactly the way it was when the backup was made. The software is typically cheap enough to pay for itself if it saves your only one or two hours of downtime.

Its 5:05PM. Do you know where YOUR backups are?

Don’t let your dollars go down a deep hole !!!!
